Below is a Letter from My Client Bruce Wallerstein, Ph.D.

In our ever growing more technologically impersonal world, it is rare to
find a blending of high tech expertise with that of a genuine and agreable
personality type. Yet when David Roller comes into your organization,
whether to your company, your office or your home, you have found that
blend.

I have been using Mr. Roller's services for over a year now, assisting me in
understanding the most foreign world of computer technology. As a novice I have been comfortably guided through a medium of which I had no knowledge. Having functioned quite effectively without computers for 34 years in a busy and productive psychological consulting firm, I realized, however, it was time to gain some level of utilization and competency in this new tool. David has not only been most helpful in that area but in so doing has performed his role in a most reliable and efficient manner. Whenever I realize that I need another tool in my now growing arsenal, David purchases the equipment and assists me in its installation along with providing the training and follow up required. More so he does it in a way that is not intimidating and with enough simplicity that even I can learn.

David is reliable, reasonable and trustworthy with your equipment, money and your mind. He returns phone calls, e mails and comes to help at unreasonable hours when you need him and does what he says he will do.

I certainly highly recommend David Roller for his knowledge, expertise and
skills in training anyone who needs assistance in the world of computer
technology.
